Absolutely NT kids can dislike school and to be honest I wouldn't be taking advice around diagnosis from people who don't know your child!
My 6 year old is the same at times. I've had to drag him in under my arm him crying and me crying - but there was always and UNMET NEED behind this, it just took time to figure it out.
These times are:
Beginning of term
End of term
Anytime he's tired
He's missing me
He's missing home
He's feeling left out at school
Change of teachers
Our solution (& I had to suggest this to the teacher who was getting abit tetchy) was
- let the school know the extent of the issue and ask if you can put a plan into together to address it. If he's late he's late but at least he's in for the first part of the plan. Our school agreed to this
- he was allowed to choose a special toy, he chose a soft toy from home, to take everyday to bridge to gap between home and school. It provided safety and security and he was allowed to ha e it on his desk or lap as long as it didn't distract him from his work.
- they have a worry doll and a quiet corner in the classroom any child can use or go to
- each child has a little person to represent them and each more ring they put it into red/amber/green/blue pegs to show how they are feeling, it can change through the day and conversations around these feelings are had if consistently red for instance.
I did propose the first two things to school instead of waiting for them as there definately was an attitude of difficult behaviour rather than WHY the behaviour might he happening (I work with adults with complex/difficult behaviours so was super tuned to this attitude!).
We have honestly gone from getting him to school being a real problem to barely any problems in the space of about 8weeks! He just feels more in control and less stripped of his own coping mechanisms that he manages with it now even if he's feeling not quite 100%> At 6 they are still so young!
The other thing that helped was taking a football into school and this seems to have bridges a gap to enable him to play with lots of others from different classes and years in school so he feels a confidence boost there aswell.
Good luck, it's really hard but there are ways andeams if a plan is put in place xx
